Description
Technical field
The utility model relates to flue gas monitoring, particularly flue gas discharge continuous monitoring system.
Background technology
Flue gas discharge continuous monitoring system, can carry out continuously real-time tracking and measuring to the particle of fixed-contamination source emission and gaseous state pollutant levels and emission index, be widely used in the factory with stationary pollution source (boiler, Industrial Stoves, incinerator).
Flue gas discharge continuous monitoring system comprise connect successively sampling probe, electrical heating sampling pipeline, pre-service treating apparatus and analytical equipment, wherein pretreatment unit comprises dehumidification system and sampling pump.Send into infrared spectrum analyser through sampling pump after the process such as working method is: flue gas is extracted out by sampling probe, then accompanies Heat transmission (preventing flue gas condensing), carries out dedusting after being transferred to flue gas analysis cabinet, dehumidifying and carry out analysis detection.
Moisture is the key factor affecting infrared instrument measurement accuracy, and existing mode is: before aspiration pump, be provided with a set of condensation de-watering apparatus, is controlled outlet sample gas dew point in certain limit by condensation de-watering apparatus.The deficiency of this mode is: when blocking occurs sample lines or other reason causes condensation de-watering apparatus place air pressure to change, outlet sample gas dew point also can change by condensation de-watering apparatus thereupon, thus causes infrared instrument measurement accuracy to be deteriorated.
Flow is the another one key factor affecting infrared instrument measurement accuracy, existing mode is: be provided with a set of sampling reflux after the condenser, sampling reflux is made up of aspiration pump and backflow bypass and metering pin valve usually, maintains desired value in order to regulate flue gas sampling flow.The deficiency of this mode is: the spinner-type flowmeter virtual height causing sampling reflux rear end, and spinner-type flowmeter shows normal flue gas sampling flow, but the problem that actual flue gas sampling flow is zero or only has little part of smoke to collect from flue.
Utility model content
In order to solve the deficiency in above-mentioned prior art, the utility model provides the high flue gas discharge continuous monitoring system of a kind of monitoring accuracy.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flue gas discharge continuous monitoring system, described monitoring system comprises sampling apparatus, analytical equipment, the first condenser, the second condenser and flowmeter; Described monitoring system comprises further:
Pump, described pump is arranged on the pipeline between described first condenser and the second condenser;
First joint, described first joint is communicated with described pump and pipeline for making the output terminal of described first condenser;
Second joint, described second joint is used for making described flowmeter be communicated with described second condenser and described pipeline;
Valve, described valve is arranged on described pipeline.
According to above-mentioned monitoring system, preferably, described monitoring system comprises further: filtrator, and described filtrator is arranged on the pipeline between described second joint and flowmeter.
Compared with prior art, the beneficial effect that the utility model has is:
1, before aspiration pump is placed in the second condenser, condensation good water removal effect, export sample gas dew point to stablize, and export the impact that sample gas dew point do not occur by sample lines to block or sample lines condition changes, thus make that the measuring error of subsequent analysis device is little, precision is high;
2, be designed with filtration snubber assembly after sampling reflow line, thus avoid sampling flow virtual height problem, thus prevent spinner-type flowmeter to make a false report the serious problems brought.
